Description
Technical Field
[0001] The present invention relates to the technical field of PCB labels, in particular to a high-heat-dissipating and corrosion-resistant PCB label. Background Art
[0002] In the field of modern battery technology, battery cells are the core components of batteries. Their performance and structural design play a decisive role in the overall efficiency of batteries. With the continuous expansion of battery application scenarios, from common portable electronic devices to large-scale energy systems such as electric vehicles and energy storage power stations, the demand for diversified battery cells has become increasingly prominent. Among them, the need for flexible adjustment of battery cell spacing has also emerged. In the assembly and application of battery modules, battery cell spacing is a key parameter. In traditional battery module design and manufacturing, battery cells are usually arranged and assembled at a fixed spacing. For example, in some early battery modules, battery cells are fixed in a predetermined position by a specific bracket or shell structure. The spacing is determined during production and is difficult to change later. This fixed spacing setting has many limitations in specific application scenarios. In order to better install and use battery cells, a high-heat dissipation and corrosion-resistant PCB label is required.
[0003] The existing battery cells cannot be adjusted in spacing during operation, and the entire battery cell cannot be shielded and protected. Therefore, a high heat dissipation and corrosion-resistant PCB label is urgently needed. Summary of the Invention
[0004] Based on this, the purpose of the present invention is to provide a high heat dissipation and corrosion-resistant PCB label to solve the problem that the existing battery cells cannot be adjusted in spacing when in use and cannot shield and protect the entire battery cell.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-heat dissipation and corrosion-resistant PCB label, comprising a polyimide film, wherein thermal grease is provided at the lower end of the polyimide film, conductive adhesive is provided at the upper end of the polyimide film, a printed layer is provided at the upper end of the conductive adhesive, and a fluorocarbon coating is coated on the upper end of the printed layer. Heat dissipation aluminum sheets are attached to the left and right ends of the polyimide film.
[0006] Preferably, the polyimide film is in close contact with the thermal grease, and the polyimide film is in close contact with the heat dissipation aluminum sheet.
[0007] Preferably, the conductive adhesive is evenly applied on the upper surface of the polyimide film.
[0008] Preferably, the conductive adhesive is adhesively connected to the printed layer.
[0009] Preferably, the surface of the printing layer is coated with fluorocarbon coating.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. The present invention provides a polyimide film, thermal grease, conductive adhesive, and heat dissipation aluminum sheet. By providing a variety of different materials, the thermal grease can be used to fill the gap between the PCB label and the heat dissipation device, improving the heat conduction efficiency and enabling heat to be more effectively transferred from the PCB label to the heat dissipation device. The conductive adhesive can be used to connect circuit components and lines, and has good conductivity, adhesion, and corrosion resistance. The heat dissipation aluminum sheet increases the heat dissipation area, accelerates heat dissipation, and improves the heat dissipation effect of the PCB label.
[0012] 2. The polyimide film and fluorocarbon coating provided in the present invention have excellent corrosion resistance, weather resistance and self-cleaning properties through the fluorocarbon coating applied on the outermost layer of the PCB label. It can resist the erosion of various chemical substances, protect the surface of the PCB label from damage, and has certain heat dissipation performance. BRIEF DESCRIPTION OF THE DRAWINGS

A conductive adhesive 3 is provided at the upper end of the polyimide film 1, and the conductive adhesive 3 is evenly applied to the upper end surface of the polyimide film 1.
